Interplay between chiral and axial symmetries in a SU(2) Nambu--Jona-Lasinio Model with the Polyakov loop

M. C. Ruivo, M. Santos, Pedro Costa +1

We consider a two flavor Polyakov--Nambu--Jona-Lasinio (PNJL) model where the Lagrangian includes an interaction term that explicitly breaks the U${}_A(1)$ anomaly. At finite tempera…
